I don't know if it is a dumb question but it bothering me for some time.
I create my 3D clothes at marvelous designer and when I import it to Blender the UV map is perfect in square size.
But for me to make it work in the game that they're made for, I need to make the UV image size at 2048x4096. When I establish the correct size, the UV stretch, and then I currently edit the scale manually.
I want to know if has some way that I can preserve the original UV size/scale from the square image when I change the image size to 2048x4096? So I don't need to change it manually, as the texture is often not perfect.
I actually using Blender 2.79
